Description

TECHNICAL FIELD

The present invention relates to a folding personal mobility vehicle, more particularly, to a technology for folding personal mobility vehicle which may be easily carried and stored even in a narrow space.

BACKGROUND

Recently, the development of single-person vehicles called personal mobility is on the rise to cope with a problem of environmental pollution and an increasing demand due to a fun to use.
As an example of a personal mobility vehicle, a carrying device called a kick board has been widely used. The kick board largely includes a foothold part provided with a wheel and a handle part provided with a handle and a length of the handle part is generally longer than that of the foothold part.
Most of the existing personal mobility vehicles including the foothold part and the handle part like the kick board do not have a folding structure, and therefore has a difficulty in carrying and take up a lot of space for storage.
As another example, a personal mobility vehicle having a length-varying structure like a sliding type has a minimum overlapping section along a longitudinal direction in which it is slid in order to secure rigidity. Therefore, as the length is not reduced to the maximum due to the overlapping section, there is still a disadvantage in that the personal mobility vehicle takes up a lot of space for storage.
As another example, a folding structure of a general hinge type has an empty space present between components that are folded to overlap. Therefore, as a volume is not reduced to the minimum even in the folded state due to the empty space, there is still a disadvantage in that the personal mobility vehicle also takes up a lot of space for storage.
The contents described as the related art have been provided only for assisting in the understanding for the background of the present invention and should not be considered as corresponding to the related art known to those skilled in the art. DE 10045821 A1 , which discloses the preamble of claim 1, shows a tread-plate of the scooter that is divided longitudinally in the middle where there is a link for folding it in two. The front and rear wheels are mounted on rocker arms. The folding link for the front part of the scooter lies above the steering-head, in front of the steering head or tube.

The lower handle part 210 and the middle handle part 220 and the upper handle part 230 and the handle 20 that are in the folded state as described above are each maintained in a folded state by the hinge locking mechanism 40. The handle part 200 is connected to the wheel carrier 30 by the hinge part 400. The hinge part 400 has a left flange 420 and a right flange 430 provided at left and right sides thereof, with an inner flange 410 interposed therebetween. The left flange 420 and the right flange 430 are connected to each other and are separated from the inner flange 410. The overlapping portion of the inner flange 410 and the left flange 420 and the right flange 430 are provided with the hinge locking mechanism 40.
